RPG Free (INFDS)

I'm trying to utilize more Free Form specs and am stuck on something.

Normally for a display file for the INFDS we declare the data structure
(focusing on PAGRRN for this issue)
D INFDS DS
D KEY 369 369
D CURLOC 370 371B 0
D PAGRRN 378 379B 0


So I'm trying to do that in Free Form and have come up with this.
DCL-DS INFDS;
KEY CHAR(1) POS(369);
CURLOC BINDEC(2) POS(370);
PAGRRN BINDEC(2:0) POS(378);
END-DS;

Something is wrong with PAGRRN portion. Is BINDEC not the same the 'B'?
The issue I have is that after paging down 9 times it give a 'target
numeric is too small to hold the results'.
If only change the program to *below* the program works fine.

DCL-DS INFDS;
KEY CHAR(1) POS(369);
CURLOC BINDEC(2) POS(370);
D PAGRRN 378 379B 0
//PAGRRN BINDEC(2:0) POS(378);
END-DS;
